'Five' in the Bible

“Yet gleanings will be left in the land [of Israel] like the shaking of the olive tree,Two or three olives on the topmost branch,Four or five on the [outermost] branches of the fruitful tree,”Declares the Lord, the God of Israel.

In that day five cities in the land of Egypt will speak the language of [the Hebrews of] Canaan and swear allegiance to the Lord of hosts. One [of them] will be called the City of Destruction.

A thousand of you will flee at the threat of one man;You will flee at the threat of five,Until you are left like a flag on the top of a mountain,And like a signal on a hill.
